The evacuations had been lifted at around 8 p.m. in the area just east of Oakley where 75 acres burned, Steve Aubert, spokesman for the East Contra Costa Fire Protection District, said.
The first report of the fire was made to firefighters at 2:14 p.m. off Tranquility Bay Road. Fortunately, the fire was burning in open vegetation, Aubert said.
No one was injured and no structures were damaged, he said.
At least one home had been threatened in the fire that was being driven by severe winds.
